Exodus 34:11

8 Then Moses quickly went down on his face in worship.

9 And he said, If now I have grace in your eyes, let the Lord go among us, for this is a stiff-necked people, and give us forgiveness for our wrongdoing and our sin, and take us for your heritage.

10 And the Lord said, See, this is what I will undertake: before the eyes of your people I will do wonders, such as have not been done in all the earth or in any nation: and all your people will see the work of the Lord, for what I am about to do for you is greatly to be feared.

11 Take care to do the orders which I give you today; I will send out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite.

12 But take care, and do not make any agreement with the people of the land where you are going, for it will be a cause of sin to you.

13 But their altars are to be overturned and their pillars broken and their images cut down:

14 For you are to be worshippers of no other god: for the Lord is a God who will not give his honour to another.
